ELECTRIC SHOCK CAN KILL! To prevent ELECTRIC SHOCK, do not perform any welding while standing,
kneeling, or lying directly on the grounded work.
6.1 Moving the torch
Torch travel refers to the movement of the torch along the weld joint and is broken into two elements: Direction and
Speed. A solid weld bead requires that the welding torch be moved steadily and at the right speed along the weld
joint. Moving the torch too fast, too slow, or erratically will prevent proper fusion or create a lumpy, uneven bead.
Travel direction is the direction the torch is moved along the weld joint in relation to the weld puddle. The torch is
either PUSHED into the weld puddle or PULLED away from the weld puddle.
For most welding jobs you will pull the torch along the weld joint to take advantage of the greater weld puddle
visibility.
Travel speed is the rate at which the torch is being pushed or pulled along the weld joint. For a fixed heat setting,
the faster the travel speed, the lower
the penetration and the lower and narrower the finished weld bead. Likewise, the slower the travel speed, the
deeper the penetration and the higher and wider the finished weld bead.
6.2 Types of welding beads
As you become more familiar with your new welder and better at laying some simple weld beads, you can begin to
try some different weld bead types.
The STRINGER BEAD is formed by traveling with the torch in a straight line while keeping the wire and nozzle
centered over the weld joint. see following figure
The WEAVE BEAD Used when you want to deposit metal over a wider space than would be possible with a
stringer bead. It is made by weaving from side to side while moving with the torch. It is best to hesitate momentarily
at each side before weaving back the other way.
6.3 Welding position
FLAT POSITION Is easiest of the welding positions and is most commonly used. It is best if you can weld in the flat
